UNITED STATES PATENT OFFICE.

CLOSURE FASTENER.

Application filed February 16, 1925, Serial No. 9,669, and. in Canada April 26, 1924.

This invention relates to closure fasteners and has for its object to provide a device that will secure a door or movable frame against the stop of the jamb.

A further object is to provide a simple, cheap and readily adjusted device adapted to make a door or the like leak proof.

A further object is to provide a means to secure a closure firmly when the surface of the closure and that of the jamb differ in level.

A further object is to provide means to secure a sliding window or door from rattling or displacement.

The invention consists briefly of a block with a series of perforations graduated in position relative to the base of the block, with means to secure it to the amb or outer frame of a closure, and a plug with a knob of resilient material turned sideways, the body of the plug adapted to enter one of the perforations. The perforations may also be made in the jamb itself or the plug may be screwed into the jamb or outer frame.

A full and complete description and specification is hereinafter given with claims attached thereto.

Reference is made to the accompanying drawings in which Figs. 1 and 1 are side views showing the closure in section.

Fig. 2 is a top view.

Fig. 3 is a perspective view in operative position.

Fig. 4 is another form of the invention.

The block 1, is of any suitable material such as hard wood or metal, and any shape providing for a series of parallel perforations 10, 11, 12, 13, at varied distances from the base 15. These perforations are of sufficient length to provide a secure support for the body 21, of the plug 2.

The block 1, is attached to the jamb or outer frame 3, by suitable means such as screws 17.

The plug 2, is preferably made of rigid metal and has a body portion 21, a bent end 22, at right angles thereto, bearing a resilient cap or knob 23.

By threading the bent end 22, of the plug 2, the cap or knob 23, may be screwed on to provide any desired adjustment.

By means of varying the shape of the bend of the plug 2, 'as shown in Figs. 1 and 2, the useful scope of the invention can be extended.

of the perforations in the block can be varied while providing graduations of distance from the base of the block.

In Figure 4, a modification is shown in which the end of the plug 2, is threaded at 25, whereby it can be screwed into the window sash 30, adjacent the sliding frame 40, of the window.

The operation of the device is as follows The block 1, having been secured to the j amb 3, at its edge or close to the edge, the door 4, having been closed, a plug 2, is inserted in one of the perforations 10, so that when turned towards the door it bears thereon with intense pressure, thereby forcing the door against the stop 31, of the jamb 3, and making a leak proof contact.

If the block 1, is secured to the jamb 3, at a distance from its edge as shown in Figure 2, the plug 2, when not in use can remain in the perforation with its bent end 22, turned side ways. The door is then free to open and shut.

If however the block 1, is close to the edge of the jamb 3, then the plug 2, must be removed to allow the door 4, full play.

It is obvious that the perforations could be made in the j amb of the door instead of the block if the edge of the jamb was a sufficient distance above the surface. of the door when closed.

WVhen the plugs are threaded as shown in Fig. 4 at 25, they can be screwed into the window sash and when turned to bear on the window frame will prevent any rattling as well as hold the frame against vertical dis placement.

This form would be adopted for use with sliding doors or panels.

What I claim is 1. In a closure fastener, the combination of a block perforated parallel to its base with a plug having a bent end and a resilient cap thereon, adapted to fit the perforation.

2. In a closure fastener the combination of a block, a series of perforations parallel to its base, means to secure the block to the jamb of a door, With a removable plug, a bent end thereto, a resilient cap thereon, adapted when inserted in one of the perforations and turned so that the cap bears on the door, to press the 10 door against the stop of the jamb.
